Adafruit customer Markus Gritsch made a great QR clock with our 1.8″ 18-bit color TFT LCD display with microSD card breakout!
being inspired by ch00ftech’s QR clock  I made my own variation of this nice idea: A PIC32 decodes the time signal from a DCF77  receiver, calculates a QR code containing this time information and displays it animated at 30 FPS on a ST7735R LCD. Without a radio signal the QR code is being displayed in b/w. A nice plasma effect is added when it locks to the DCF77 signal.
